  1. OVERWEIGHT AND OBESITY IN ASSOCIATION WITH PHYSICAL ACTIVITY AND EATING HABITS AMONG BUS DRIVERS IN NAIROBI. MORURI IMMACULATE EDELA90/0142/2008 SUPERVISOR PROF J.K IMUNGI

  2. Statement of the problem • The prevalence of obesity has been increasing both in developed and developing countries, and more noticeably in urban areas. (Abubakari et al, 2008) • National data on prevalence of adult men in Kenya is lacking. • A documented study on the prevalence of overweight and obesity among adults needs to be done to facilitate proper interventions and management strategies.

  3. Justification • Metropolitan bus drivers are at high risk of being overweight or obese due to reduced physical activity and poor dietary intake. • Structural variables that encourage this obesogenic environment include long work hours and lack of scheduled breaks. • This study thus concerns itself with determining the prevalence of overweight and obesity among bus drivers in association with their dietary intake and physical activity.

  4. Aim • to contribute towards improving the health status among bus drivers. Purpose • to contribute to information on the prevalence of obesity in relation to eating habits, physical activity and nutritional status.

  5. Main objective • to determine the prevalence of overweight and obesity in association with physical activity and eating habits among metropolitan bus drivers in Nairobi, Kenya.

  6. Sub-objectives • To determine the physical activity level of the study bus drivers in Nairobi, Kenya. • To assess the eating habits, smoking habits and alcohol intake of the study drivers. • To determine the Body Mass Index of the bus drivers. • To describe the socio-demographic and socio-economic characteristics of the bus drivers .

  7. DESIGN • Sample Size Determination • At 95% confidence interval using Fischer formula (Fischer et al. 1991) • N = (Z2 p q) / d2 • Where p = 7.7%, q = 92.3%, z= 1.96, d=0.08 • N = 43 • When 20% attrition is added sample size = 52 bus drivers

  8. Sampling procedure Bus and commuter companies 100 Citi hoppa bus drivers 200 double M bus drivers Sample of 14 bus drivers Sample of 38 bus drivers

  9. METHODOLOGY • Semi-structured questionnaire • Demographic and socio-economic information • food frequency questionnaire • Physical activity questionnaire • Anthropometry measurements

  10. RESULTS

  11. RESULTS cont…

  12. BMI and frequency of fast food consumption

  13. Weekly frequency of consumption by BMI

  14. BMI and alcohol consumption

  15. Distribution of BMI and smoking habits

  16. Distribution of drivers by weight

  17. Physical activity level of the drivers

  18. Conclusion • Overweight and obesity is highly prevalent among bus drivers in Nairobi with the highest proportion being in the 31-38 years age group. • Lack of physical activity is associated with overweight and/or obesity among bus drivers. • The relationship between alcohol consumption, smoking habits and nutritional status of the drivers is statistically significant.

  19. Recommendations • Nutritious foods be made available to the drivers at their work place. • Provision of nutrition education to the drivers to make them aware of the practices that lead to overweight and obesity so as to enforce nutrition conscious decisions. • Encouragement of physical activity or coming up with simple policy guidelines which should include the health benefits of reducing or breaking up prolonged sitting time.
